The coach was appropriate. As a common rule, you need to keep away from any train that requires pulling or pushing a weight behind the neck. The issue with these strikes is that they place the shoulder joint in a biomechanically disadvantageous place. As a result of the shoulder joint is so cellular – with freedom in all planes of motion – it is usually extremely unstable (elevated joint flexibility essentially leads to decreased stability).
Within the end place of the behind-the-neck lat pulldown, the humerus (higher arm bone) is compelled again in a fashion that concurrently causes excessive abduction and exterior rotation of the shoulder joint. This locations an excessive amount of stress on the shoulder capsule, which might trigger injury to smooth tissue buildings, particularly the small rotator cuff muscle mass. Worse, repeated use of the train may cause stretching of the shoulder joint ligaments, rising the possibility of everlasting deformation. Over time, the ligaments can grow to be so unfastened that surgical procedure is required to reinstate stability, setting again your coaching efforts for months.
There’s additionally an inclination to tug the neck ahead and downward throughout efficiency, rising the prospect of harm to the cervical backbone and corresponding muscle mass and ligaments. There may be even the hazard of vertebral trauma if the bar is pulled down too arduous on the spinous course of. Given the truth that research have proven the behind-the-neck model is much less efficient than different variations of lat pulldowns, there isn’t any purpose to incorporate it as a part of your coaching arsenal.
